It takes a long time to get from the Neanderthals to the Homo Sapiens. And so it will probably take a long time to make this game really playable. It offers a lot of potential, but it is currently (0.72) in a very rough version.
I managed to get into the second level of the first age before I quit the game. Why:
1. The characters, whether PC or NPC, urgently need a better body model.
Especially in the sex scenes, when you have lost the fight, very unsightly proportions arise.
1.1. When working on the body model, it may even be a good idea to be able to adapt your own PC.
I understand that changing the body shape would require a lot of additional animation and would therefore not be feasible in the beginning. But cosmetic modifications would be very nice.
Skyrim also runs with the same engine. Take a look at the CBBE models.
2. I haven't even managed to pick up a gun in several attempts. [E] worked to put on the armor (why does it go away when you change levels?), But I was unable to take a wake on defeated opponents despite the response.
2.1. It also looks as if the weapon selection is predetermined. In the first card I could only have picked up the first stick and apparently could no longer change the weapon because the display of other defeated opponents was missing. So I could only have picked up the spear in the second section of the map, but that didn't work either.
3. The speed of the PC. If possible, this should be increased by 25-33%. Normal running is very slow.
4. If possible, there should still be usable items. For example, around the campfire in the Essen cave, which could regenerate lost life points
